Transformer issue?

[radio nut]

I recapped a Zenith 7Ao2 chassis a while back...turned the set on and it played...well. After about 20 minutes it made a loud pop noise in the speaker and quit, dead silence.I checked voltages and found zero volts on one leg of the high voltage. The other leg was very high, about double what it should have been. I thought the transformer went out. I just got to looking at it again after about a year and found a wire that the coating crumbled off and is now touching the metal chassis. Could that cause my voltage readings if it was the " correct" shorted wire? I took care of the shorted wire and was going to fire it up but I dropped the rectifier tube and don't have a back up tube.
